KNITTIVNG-MACHINE.

SPECIFICATION forming part of vLetters Patent No. 331,402, dated December 1, 1885.

Application filed reburary 19,1885.

.To all whom t may concern.-

Beit known that I, WARREN D. HUsE, of Laconia, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Circular-Knitting Machines, of which the following, taken in connection with the accompanying drawings, is a speoication.

My invention relates to knitting-machines, and particularly to that class of knitting-machines in which a series of latch-needles are arranged so as to be moved endwise by a cam to form the stitches which constitute knitting; and it consists in certain novel features and arrangements of parts, whereby the lower ends of the needles may be moved laterally by swinging about a xed fulcrum or axis at or near the hook'end of said needles, so that the lugs secured to or formed upon said needlesmay be removed from the path of the cam whenever it is desired to throw the said needles out of action, all of which will readily be understood by reference to the description of the drawings, and to the claims to be hereinafter given.

Of the drawings, Figure l represents a central vertical section of a portion of a circularknitting machine embodying my invention. Fig. 2 represents a horizontal section of a portion of same, the cutting-plane being on line x :v on Fig. l. Fig. 3 represents a central vertical section of a portion of a circular-knitting machine embodying a modiiied form of my inv'ention; and Fig. 4 represents a horizontal section of a portion of the same, the cuttingplane being on line y y on Fig. 3.

A is the needle-cylinder, rmly secured to the base-ring B in any suitable manner, and it has formed in its periphery a series of ver# tical grooves, a a, to receive and form guides for the needles G C. The needles C C are each provided with a lug, b, which projects outwardly into and is acted upon by the campath c ofthe cam-cylinder D,which is provided with the bevel gear-teeth E, to which rotary motion is imparted by a suitable bevel gearwheel (not shown) in a well-known manner. The rotation of the cam-cylinder D imparts to the needles C C an endwise reciprocating 5o movement through the medium of the campath c, and the lugs Z b, also, in a well-known Serial No. 156,338. (No model.)

' manner. The annular plate F, mounted upon the cylinder A by a driving iit, has a recess,G, in which the two segmental plates H and H', placed one above the other, each provided at each end with -the cam-like curve t3 it, are adapted to be operated by means of the plates I, the eccentric l', the two double-ended pawls J J', 85o., all as has been fully described in a pending application of mine, filed July 21, 6o 1884, and numbered 138,349, and therefore need not be described more at length here. The grooves a a have their inner walls so inclined that said groovesV are considerably deeper at their lower than at their upper ends, 6 5 and the partitions between said grooves a a are cutaway midway of their lengths, so as to form the annular groove d, in which the segmental plates H H act against the needles C C when pressing said needles out of action. A spring, 7o K, is placed in contact with the needle C in such a manner that it will always tend to keep the said needle in contact with the cam-cylinder D and the lug b in the cam -path o. rlhe spring K may be placed within the groove a in a recess, e, made for that purpose, as shown in Figs. l and 2; or it may be placed between the cylinder A and the inner cylinder, L, which isV provided with as many vertical grooves f f in its periphery as there are 8o grooves c a in the periphery of the cylinder A, said grooves f f serving as guides to prevent the turning of the spring K, one end of which extends lengthwise of said groove, while the other end is bent horizontally, and, passing through the hole g, its extreme outer end presses against the inner side of the needle C with the tendency of keeping said needle in contact with the cam-ring D.

When it is desirous of throwing any of the 9o needles G out of action, the segmental plates H H are moved against them by mechanism substantially such as shown and described, or equivalents therefor, to such an extent that said needles are swung about a fulcrum, as at 9 5 h, until the said needles come into contact with the inner walls of the grooves a c at the upper and lowerportio'ns thereof, the springs K being compressed to allow of such movement. lt has been found by experiment to be of adroo vantage to thus remove the needle from action without bending the needle, as no damage is liable to be done thereto, as is the case when the needle is bent midway of its length, for in practice the needles were often broken at the bend in the lug by the. repeated bending and cramping of the needle-shank.

I am aware that knitting -machine needles have been thrown out of action by swinging them about a fulcrum at or near their hook ends, as in the Patent No. 140,800, of July 15, 1873, and in Patent No. 214,308, of April 15, 1879, and also that a spring has been used to throwa needle so thrown out of laction into action again with its cam, as in English Patent No. 2,729 of 1871, and thereforel do not claim, broadly, throwing a needle out of action with iis cam by swinging it around a fulcrum at or near its hook end, or throwing` it into action again by means of a spring; but

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. The needle-cylinder A,provided with the grooves a a, made deeper at their lower than at their upper ends,the needles C G, provided with the lugs b b, the cam-cylinder D, provided with the cam-path @,the segmental plates H H', adapted to be moved against said needles, so

as to throw them out of action, and the springs K K, adapted to press said needles into contact with said cam-path, substantially as described.

2. The needlecylinder A, provided with the grooves a a, made deeper at their lower` than at their upper ends, in combination with the needles C C, provided with the lugs b b, the cam-cylinder D, provided with the cam-path c, the segmental cams H H', adapted to be moved against said needles, so as to throw them out of action, the cylinder L, provided with the longitudinal grooves fand secured to the interior of the cylinder A, and the springs K, inserted between said cylinders A and L and extending through openings in said cylinder A into contact with the needles y C, substantially as shown and described.

In vtestimony whereof l have signed my 45 naine to this specification, in the presence of two subscribing witnesses, on this 2d day of January, A D. 1885.
